Window with rotating movable frame

ABSTRACT

A pivoting window frame is provided having a mobile part provided with two coaxial pivots that slide transversally upon section steel pieces attached to a fixed part. The mobile part of the window can be moved between an extreme interior position, where it can be applied in a tight manner against the fixed part, and an opposite exterior position, in which it is sufficiently far away from the fixed part so as no longer to butt against the latter and so as to be able to pivot freely by at least one complete turn. The lateral posts of the fixed part present a retractable marginal element between a protruding position, in which it ensures the lateral tightness of the closed window, and a retracted position, in which it permits the free pivoting of the mobile part.

SHEEI 0F 5 FIEL4 WINDOW WITH ROTATING MOVABLE FRAME BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relatesto a pivoting window, comprising a mobile part, provided with two coaxial pivots, preferably situated essentially halfway up along the window height and sliding transversally. The mobile part of the window thus can be moved between an extreme interior position, in which it can be applied against a fixed part of the window, in order to ensure the closing of the latter, and an opposite exterior position, in which it is disengaged from and sufficiently far away from the fixed part so as no longer to abutt against the latter and so as to be able to pivot freely by at least one complete turn. The lateral posts of the fixed part of the window provide at least a marginal element which is retractable between a protruding position in which it guarantees the lateral tightness of the closed window and a retracted posiiton in which it permits the free pivoting of the mobile part.

2. Description of the Prior Art In known windows of this kind, such as Belgian Pat. No. 743,059 (1969), the swinging pivots of the mobile part are each engaged in transversal slides of the fixed part and are each provided with a roller or runner which rolls on the bottom of the corresponding slide.

The presence of a roller near the end of each pivot confers upon known windows an inconvenience which is due to the small lateral leeway of this roller or runner in the slide. In effect, the roller in question is rapidly wedged in the slide, the moment the mobile part is moved, during the process of being slightly inclined with respect to the plane of the entire window assembly.

SUMMARY OF THE INVENTION The object of this invention is to provide an improved window, making it possible to remedy the abovementioned inconveniences in known windows of this kind. Furthermore, the window of the present inven tionhas a simpler and less expensive construction than the earlier ones, with regard to its swinging pivots, their supports and their housings.

For this purpose, in a pivoting window according to the invention, each pivot of the mobile part rests simply on a fixed piece of section steel mounted on the fixed part of the window.

In order to obtain a zone of minimum friction of the pivot upon the supporting piece of section steel, the latter provides a support ridge for this pivot.

Advantageously, the supporting piece of section steel for the pivot is adjustable in a position parallel to the plane of the window and/or in terms of height.

To guarantee its easy replacement, the supporting piece of section steel for the pivot is mounted in a removable manner on the fixed part of the window. Gen erally, the supporting section steel of the pivot is mounted in a transversal recess presented by the fixed part of the window.

For the purpose of keeping the mobile part of the window in its extreme positions, the above-mentioned pivots may be maintained in their corresponding positions in order to be able to turn around their axis without sliding in these positions.

According to another feature of the invention, the retractable marginal element of each lateral post of the fixed part is mounted preferably upon this post, and is capable of pivoting horizontally around the remaining part of the post.

According to another feature of the invention, the retractable marginal element of each post of the fixed part is preferably mounted on the corresponding post of the mobile part, being able to slide parallel to the plane of the window with respect to the remaining part of this latter post.

FIG. 4 is a partial plan view cross-section of a second version of the pivoting window according to the invention, and

FIG. 5 is a similar plan view cross-section of a third version of the pivoting window according to the invention.

In these various figures, the same reference numerals refer to identical elements.

DESCRIPTION OF THE PREFERRED EMBODIMENT The pivoting window according to the invention essentially comprises a fixed part which comes in one piece with the wall 1 of a building and a mobile part arranged in this fixed part and pivoting verticaly with respect to the latter.

The fixed part essentially consists of a fixed frame 2 which presents two lateral recesses 3 halfway along the height.

Each recessed part 4 of the fixed frame 2, which forms the bottom of the transversal recess 3, carries two bolts 5 which are welded and which are at the same level. Each bolt 5 supports a particular piece of section steel 6 by means of an exterior screw 7, an interior screw 8, and a bracing ring or washer 9.

The two section steel pieces 6, arranged laterally, one opposite the other, in fact serve to support the mobile part of the window.

Each section steel piece 6 thus attached to the recessed part 4 of fixed frame 2 can be considered as consisting of the following: a plane web 10, arranged vertically, a lower, likewise plane flange 11, which however isfolded at a right angle with respect to the web 10 and which is thus arranged horizontally, and an upper flange I2, comprising three component parts which are successively folded at a right angle but each of which is inclined at 45 with respect to the web 10.

Each section steel piece 6 is arranged transversally with respect to the plane 'of the window assembly. The section steel piece 6 is placed opposite the transversal recess 3 with its web 10 parallel to the recessed part 4 constituting the bottom of this recess 3 and slightly outside the latter, with regard to the fixed frame 2. The

particular shape of the upper flange 12 of each section steel piece 6 determines an upper, more or less rounded ridge 13.

It should be noted that the position of each section steel piece 6 is adjustable with respect to the recessed part 4 of fixed frame 2, along 'the axes of the bolts 5, that is to say, along a horizontal axis which is parallel to the plane of the window assembly. This is so because the adjustable positioning of the two tightening screws 7 and 8 of section piece 6, on each bolt 5.

Furthermore, each section steel piece 6 is also adjustable in terms of height, that is to say, vertically and parallel to the recessed part 4 of fixed frame 2. For this purpose, two vertical threaded rods 14 connect the screws 7 of bolts to the lower flange ll of section steel piece 6. Thus, each threaded rod 14 traverses a corresponding opening of the bracing washer 9 and is supported against the screw 7. Threaded rod 14 goes through an opening in the lower flange 11 of section steel piece 6 and is blocked, with respect to flange 11, by means of two nuts 15. The height positioning of the two nuts 15 guarantees the vertical regulation of steel piece 6.

In the first version, as seen in FIG. 1, the mobile part of the window comprises a mobile wooden frame 16 in which is mounted, for example, a single or double glass pane 17, held in place by glasswork slats 18.

The mobile part of the window pivots vertically in the fixed part of the latter. For this purpose, the mobile frame 16 carries two horizontal, lateral, and coaxial pivots 19, arranged halfway up along the height and resting, respectively, on ridges 13 of the two pieces of section steel 6 which are mounted the fixed frame 2.

On the other hand, each pivot 19, for example, presents a tronconic base 20 by which it is attached upon the mobile frame 16 by means of a blocking U-bolt 21 which is attached to this mobile frame 16 by screws 22.

As described above, the pivots 19 of mobile frame 16 rest, respectively, on section steel pieces 6 which are attached to the fixed frame 2. The mountings of the .pivots 19 upon the section steel pieces 6 result solely from the simply support of each pivot 19 upon ridge 13 of the corresponding piece of section steel 6.

Since each section steel piece 6 extends over a large part of the transversal width of wall 1, each pivot 19 is thus practically movable from one edge of this wall 1 to the other, being able to slide upon this piece of section steel 6.

In order to limit the transversal movement of each pivot 19, there is provided an arresting U-bolt 23 whose descending wings in fact constitute stops for this pivot 19.

As illustrated especially in FIG. 2, each pivot 19 presents a relatively great lateral leeway with respect to the recessed part 4 of the fixed frame 2. Thus, the mobile part of thewindow, particularly, mobile frame 16, can be moved without difficulty between two extreme positions, an interior postion and an exterior position, either remaining parallel to the plane of the window assembly or being slightly inclined with respect to that plane.

In the extreme interior position, the mobile frame 16 is applied continually, in a tight manner, against the posts and the interior rails that are a part of fixed frame 2, in order thus to guarantee the closing of the window. When the window is in this closing position, the mobile frame 16 is supported on its circumference against the continuous sealing joints 24 which are arranged in appropriate notches in these interior posts and interior rails.

In the extreme exterior position, frame 16 is removed from the above-mentioned interior posts and rails. These posts each include a vertical stationary element 25 which is attached to wall 1 and a vertical retractable element 26, mounted so that it can pivot with respect to the stationary element 25 with the help ofa hinge 27. Because of this, when in the closing position, the retractable element 26 is aligned with stationary element 25 and is opposite the corresponding post of the mobile frame 16. But, in the opposite opening position, the retractable element 26 may be retracted and flanged internally against the stationary element 25 and may be offset from the wall 1 with respect to the corresponding post of the mobile frame 16. It follows from this that, in the above-mentioned opening position, mobile frame 16 may turn vertically by at least one complete turn around the common horizontal axis of pivots 19.

The second embodiment of the window differs essentially from the first one by virtue of the fact that the fixed and mobile frames are made up of metallic section steel pieces, instead of being made of wood.

In this case, the posts and the rails of the mobile frame 16 are formed by section steel-pieces 28 in the shape of a U whose inwardly directed flanges surround the edges of the glass pane l7 and whose webs carry continuous sealing joints 29, except at the horizontal pivots l9.

In this second example, the stationary element 25 of each post of fixed frame 2 is made up primarily of an angle-iron, whereas the retractable element 26 of this post is formed by a tubular section steel piece with a rectangular section, connected to the former bya hinge 27.

It should also be noted that, in the second case, the end stops for the movement of the horizontal pivots 19 are made up, externally, of a vertical plate 30 which comes in one piece with the fixed frame 2 and, internally, by another vertical plate 31, which is less wide and attached, for example, to the stationary element 25 of the corresponding post of this fixed frame 2.

The third embodiment of the window differs essentially from the preceding one by virtue of the post and rails of the fixed frame 2 which here constitute the window frame.

In this case, each post and each rail of the fixed frame 2 is made up of a single metal section piece having a transversal cross-section, for example, which is essentially square. The section piece 32 of each post, however, presents a vertical longitudinal slot 33 at whose bottom there is placed a continuous sealing joint 34.

Each post 28 of the mobile frame 16 carries a thin mobile plate 35 mounted in a U-shaped support 36, one of whose flanges is applied against the section piece 28 by an intermediate piece 37. Due to the action of an operating handle 38 and with the help of transmission means, not shown and known in themselves, thin plate 35 can be moved parallel to the plane of the window assembly, between the retracted and the protruding positions. In the retracted position, thin plate 35 is completely between the wings of its U-shaped support 36 and does not stick out beyond the corresponding edge of the mobile frame 16. In the protruding position, thin plate 35 is partly disengaged from its support 36 and is introduced into the notch 33 of the section piece 32, all

the way against the sealing joint34. It can be seen that, in the retracted position, thin plate 35 does not interfere with the vertical rotation of the mobile frame 16 when the window is in the open position. In the protruding position, thin plate 35 is applied against the sealing joint 34, thereby ensuring the tightness of the closed window when the mobile frame 16 is placed in the closing position. i
